Modified kaolin

After special treatment of coal measures kaolin, the specific surface area is increased, and then the surface modification treatment can greatly improve the reinforcing effect of rubber. In the application of rubber products such as automobile tires and EPDM, the reinforcing performance of coal measures kaolin can reach or even exceed that of carbon black or white carbon black in some aspects.

Fly ash type rubber reinforcing agent

Glass beads separated from fly ash are filled into polyvinyl chloride (PVC) to improve performance and reduce costs. A new rubber reinforcing agent (XRF) with fly ash as the main material developed by Beijing University of Chemical Technology has been applied in Beijing No.2 Rubber Plant. A large number of experiments have proved that the new rubber reinforcing agent (XRF) in natural rubber, synthetic rubber (styrene butadiene rubber, nitrile butadiene rubber, epDM rubber, neoprene rubber, etc.) application performance has completely reached the same level to replace the semi-reinforced carbon black. This technology not only solves the environmental hazards caused by the accumulation of a large amount of fly ash, but also makes a great contribution to the conservation of resources.

Attapulgite modified clay

The attapulgite is composed of silicon and aluminum oxides, with a small amount of iron, calcium and manganese oxides. White fibrous crystal is a semi-reinforcing filler, which can make the surface of extrusion calendered rubber smooth. New high quality rubber reinforcing agent attapulgite modified clay can increase the constant elongation stress of rubber products by 300%, improve the elongation at break, eat powder fast, dust is not easy to fly, has the characteristics of high whiteness, high dispersion, high covering power. Adding this product to rubber products can not only improve the appearance quality, delay the aging rate, but also be able to resist acid and alkali corrosion and reduce the cost. It is an excellent rubber reinforcing agent. It can be widely used in rubber belt, automobile tire and other rubber products.

Modified hard clay

The hard clay has a semi-reinforcing effect in rubber and can improve the mechanical properties of vulcanized rubber. Soft clay has no reinforcing effect in rubber. By modifying the clay with stearic acid, vinyl silane, hydrogen silane and titanate coupling agent, the surface of the clay can increase hydrophobicity, and the tensile strength and constant elongation stress of the rubber can be improved, and the permanent deformation of heat production and compression can be reduced. The reinforcing property of the clay is similar to that of silica, and the aging property is good. Superfine reactive clay SFAC, a new reinforcing agent, has the same effect as semi-reinforcing carbon black.

Rice husk rubber reinforcing agent

Using rice husk as raw material, it is a kind of rubber reinforcing agent made by coupling activation. It is mainly used for glass, paint, paper, rubber and plastic products.

Plastic base rubber reinforcing filler

, based on polyolefin plastic and heavy CaCO3 powder, calcium magnesium powder and a variety of high performance surfactant, multilayer coating technology to produce high performance plastic rubber reinforcing filler, the reinforcing filler has good liquidity, can under the filling quantity of higher applied to natural rubber as the main variety of miscellaneous pieces of rubber of rubber, Such as rubber V belt, rubber seals, rubber roller, rubber liner, rubber hose, rubber plate, etc.

Lignin rubber reinforcing agent

Lignin is prepared by direct modification in the waste liquid of papermaking and pulping. New rubber processing technology is adopted to make the penetration and cross-linking between rubber and lignin reach the molecular level, so that the alloy composed of rubber and natural polymer compound (lignin) has excellent comprehensive properties. Its mechanical properties and high wear - resistant furnace method of carbon black, the ratio of rubber is twice higher than carbon black.

Nanometer zinc oxide

Nanometer zinc oxide is a white or slightly yellow powder, easy to disperse in rubber and latex, is a natural rubber and synthetic rubber reinforcing agent, active agent and vulcanization agent, is also a white glue colorant and filler. After adding active zinc oxide to the rubber material, the rubber can have good wear resistance, tear resistance and elasticity.

Sepiolite rubber reinforcing agent

The chemical composition of sepiolite is a hydrate of silica and magnesium oxide with small amounts of aluminum and iron oxides. It is used as reinforcing agent in light colored rubber products, and its performance is only second to that of white carbon black. When treated with silane, the reinforcing performance of seolite powder is close to that of silica, and the price is only half of that of silica. It is resistant to acid and alkali, chemical corrosion, in rubber, plastic products dispersion performance is good, is an ideal filling reinforcing agent in rubber, plastic products. It is better to use in natural rubber, can greatly reduce the cost, improve product quality and economic benefit.

Magnesium carbonate

Magnesium carbonate is mainly used as filler and reinforcing agent for rubber products, which can increase luster, whiteness, high temperature resistance, and is insulation material.

Modified bentonite

Is made of natural bentonite and modified bentonite made from modifying agent and other additives, has the strong adsorption and cation exchange capacity, mainly used as filling agent and reinforcing agent of various rubber can improve the performance of rubber products, reduce the cost of rubber products, improve the bonding strength of rubber and cord and rubber processing performance.

Zeolite powder

Zeolite powder is a kind of non-metallic mineral, because of its very unique mineral structure, can be used as a variety of rubber filler and reinforcing agent, improve the performance of rubber products

Mica powder

Sericite has the reinforcing effect, can replace part of the semi-reinforcing carbon black, can also be used as an isolating agent. Because it belongs to monoclinic crystal system, its crystal is thin sheet, so it can improve the damping property of rubber. It has good heat and acid resistance and electrical insulation performance, as well as the function of uv and radioactive radiation, can be used for special rubber products.

Coal gangue powder

The chemical composition of coal gangue 5 is similar to kaolin, which is a mixture of alumina, silica and magnesium oxide. The volatile component of coal gangue 5 is up to 27% and has semi-reinforcing effect. It is commonly known as silicon aluminum carbon black. Easily mixed into rubber, good dispersion, can replace part of carbon black as reinforcing agent.
